Mengatur jalur ke runtime bahasa umum (CLR) yang dimuat dalam debugger.

Sintaks

int SetCorPath(
   string pcstrCorPath
);

Parameter

pcstrCorPath
[di] Jalur ke CLR yang dimuat di debugger.

Tampilkan Nilai

Jika berhasil, mengembalikan S_OK; jika tidak, mengembalikan kode galat.

Contoh

Contoh berikut menunjukkan cara menerapkan metode ini untuk objek ExpressionEvaluatorPackage yang mengekspos antarmuka IDebugExpressionEvaluator2 .
